John McCain isn’t quite sure how many houses he owns, Politico reports. The presumptive Republican nominee responded to the question in yesterday’s interview with “I think—I’ll have my staff get to you.” He and wife Cindy are estimated to own between four and seven properties. Barack Obama’s campaign was swift to capitalize, producing an ad today capped by a shot of the White House and the narration “Here's ONE house America can't afford to let John McCain move into.”

In the same interview, McCain, 71, definitively stated that he would not pledge to serve only one term if elected. “I’m not considering it,” McCain said of the one-and-done pledge, which some insiders said might calm concerns about his age.
